#159042 - return value? Responding to: ???'s previous message |
A tab is a single character. It is the receiving end - your terminal - that makes the decision how wide to display the tab character.
But you should avoid counting numbers. If a byte is larger than 99, then it doesn't matter if you have requested the output to be two characters wide. One alternative - if you have the room and need the width before - is to use sprintf() and then eval strlen() or use the return value from sprintf(). I haven't checked the C51 RTL manual, but the standard printf() function is expected to return the number of printed characters - if it is enough to learn the number of characters after the write. |

| Not entirely true? | 01/01/70 00:00 | |
| You are correct | 01/01/70 00:00 | |
